Boats float because of the principles of displacement and buoyancy, first described by the Greek philosopher Archimedes. Displacement tells us that because water is incompressible, objects...

How does a heavy boat float? ... A boat, or any other object designed to float, is based on a theory by a very old guy, even older than Capt. Matt. Though he is old and, by the way, dead, he was really a cool guy and his name was Archimedes (Ark-i'-meed-eez). ... Find out why some boats ride through the water and some ride on top.

It is this upward water pressure pushing on the bottom of the boat that is causing the boat to float. Each square inch (or square centimeter) of the boat that is underwater has water pressure pushing it upward, and this combined pressure floats the boat.

10 It will stay the same because ice is the same amount of the water it started as, so therefore when it melts the glass of water will have the same water level. - anon48013 9 When water freezes it increases in volume about 9%. The ice cube...

Why boats float and elephants sink (buoyancy) ... How does a boat or ship carrying hundreds of pounds worth of stuff float while that same stuff would sink to the bottom of the ocean if dumped overboard? How come when you're in a pool and you stretch your body out flat you float.

Well, when thinking about floating and sinking you must think about something that is called buoyancy. This is the force that helps objects float. The actual act of floating has to do with pressure rather than weight.

Buoyancy is the loss in weight an object seems to undergo when placed in a liquid, as compared to its weight in air. Archimedes' principle states that an object fully or partly immersed in a liquid is buoyed upward by a force equal to the weight of the liquid displaced ...

A boat floats, because the fluid in which it is floating offsets the downward pull of gravity and pushes it up. ... Despite the enormous size of some ships, they are basically metal shells filled with air, and are less dense and lighter than the water they push aside, which allows the boats to float.
